MATLAB for Machine Learning

By: Giuseppe Ciaburro

Overview of this book

MATLAB is the language of choice for many researchers and mathematics experts for machine learning. This book will help you build a foundation in machine learning using MATLAB for beginners. You’ll start by getting your system ready with t he MATLAB environment for machine learning and you’ll see how to easily interact with the Matlab workspace. We’ll then move on to data cleansing, mining and analyzing various data types in machine learning and you’ll see how to display data values on a plot. Next, you’ll get to know about the different types of regression techniques and how to apply them to your data using the MATLAB functions. You’ll understand the basic concepts of neural networks and perform data fitting, pattern recognition, and clustering analysis. Finally, you’ll explore feature selection and extraction techniques for dimensionality reduction for performance improvement. At the end of the book, you will learn to put it all together into real-world cases covering major machine learning algorithms and be comfortable in performing machine learning with MATLAB.

A neural network getting started GUI

A GUI is an interface that allows users to interact with computers through graphical icons and visual indicators instead of text-based interfaces. GUIs were introduced to make interactive operations more convenient in comparison to the more challenging procedures required by command-line interfaces, which require commands to be typed on a computer keyboard. The actions in a GUI are usually performed through direct manipulation of the graphical elements.

To make the application of neural networks as simple as possible, the toolbox gives us a series of GUIs. Seeing is believing. The main one is the nnstart() function, which opens a window with launch buttons for neural network fitting, pattern recognition, clustering, and time series tools:

>> nnstart

This command opens the Neural Network Start GUI, as shown in the following figure:

This GUI represents the dashboard of the entire toolbox, in the sense that, from...
